Steam Deck pass-through (design/steam-deck-passthrough-plan.md), code-complete + all CI checks green on Linux + adversarially reviewed; on-glass validation pending: - usbip/`vhci_hcd` virtual Deck transport (inject/linux/steam_usbip.rs) for non-SteamOS hosts (Bazzite/generic) — presents a real interface-2 USB Deck so Steam Input promotes it. In-process vhci attach (loopback OP_REQ_IMPORT handshake → sysfs attach) with a bounded `usbip`-CLI fallback; detach on drop. - Backed by a vendored, libusb-free trim of the `usbip` crate (crates/punktfunk-host/vendor/usbip-sim, MIT + NOTICE; host/cdc/hid + rusb/nusb removed; interrupt-IN paced by bInterval). - Selection ladder raw_gadget (SteamOS fast-path) → usbip (universal) → UHID, with PUNKTFUNK_STEAM_USBIP / PUNKTFUNK_USBIP_ATTACH knobs. - Shared Deck descriptors + the 0x83/0xAE feature contract + a Steam-accepted serial consolidated into steam_proto.rs; the raw_gadget backend reuses them. - Linux client leave-shortcuts: Ctrl+Alt+Shift+D + holding the escape chord (L1+R1+Start+Select) >=1.5s end the session (short press still exits fullscreen); the chord state resets across sessions. Also bundles in-progress work already staged in the tree: - host(kwin): xdg-output logical-geometry mapping so the KWin fake_input backend places absolute coordinates correctly under display scaling. - docs: design/README index entries + design/controller-only-mode.md.

# Vendored + trimmed copy of the `usbip` crate (jiegec/usbip v0.8.0, MIT), reduced to the
|
|
# USB/IP *server simulation* path only: we present a virtual Steam Deck and let the local
|
|
# `vhci_hcd` attach it. The upstream crate hard-depends on `rusb`→`libusb1-sys` (for its USB
|
|
# *host* mode, which we do not use and which would add a libusb runtime dep + break `musl`),
|
|
# so the host modules (`host.rs`, the `rusb`/`nusb` device constructors) and the helper
|
|
# interface handlers (`cdc.rs`/`hid.rs`) are removed. What remains — the device model, the
|
|
# USB/IP protocol framing, and the `UsbInterfaceHandler` trait — is pure `std` + `tokio` and
|
|
# carries no libusb dependency. See `NOTICE` for upstream attribution.
